The HOLD? query returns an integer value representing the status of the wavelength
measurement in the OMM-6810B.
Parameters None.
Response
where the response data is an integer value as shown:
0 = unit is currently making stable wavelength measurements
1 = unit is currently holding the wavelength measurement because the input signal is too
unstable to accurately measure the wavelength; wavelength measurements will return
when the input source is stable again.
2 = unit is not measuring wavelength; either the WAVELENGTH AUTO measure has
been disabled by the user or the measurement head is not capable of wavelength
measurement.
Note This command can be used to determine the state of the wavelength measurement
feature in the OMM-6810B. This query is the same as viewing the HOLD indicator on the
front panel.
Example “HOLD?” - response: 1, means the unit is holding a wavelength but will return to
wavelength measurements when the input becomes stable.
